BVFH40 French Bureau of Shipping certification, BV-FH40 low-temperature ship plate fixed rolling, BV

BVFH40 is a French classification society certified ship plate, BVFH40 high-strength ship plate steel has high requirements for low temperature toughness and welding performance, so it adopts the composition design idea of low c, high Mn content and the addition of Nb and Ti microalloying elements.

The alloying elements and fine grain elements Al, Nb, V, Ti added should comply with the relevant standards recognized or recognized by classification societies, and the crack sensitivity coefficient Pcm should be calculated using a formula instead of carbon equivalent, and its value should meet the standards recognized by classification societies.

BV-FH40 Production Specification Range:

The specification range that can be produced on board is 5-80mm x 1500 -3900mm x 3000-12000mm. Most manufacturers can only produce ship boards with a thickness of less than 30 mm and a width of less than 2,200 mm. Wugang is called a wide and thick variety of steel, which can produce more than 220 ship plates, and can also be certified by classification societies.

BV-FH40 steel plate production and cutting process:

production process: initial refining →LF refining→ VD treatment→ continuous casting (die casting) → cleaning, heating→ rolling → (stacking) → surface inspection→ batch → flaw detection→ heat treatment→ cutting sampling→ performance inspection → warehousing.

BV-FH40 ship plate is a high-strength ship plate, which can produce marine steel with different national specifications according to user needs, such as the United States, Norway, Japan, Germany, France, etc., and its specifications are as follows:
